ORLANDO J. BOOS, OF LOS ANGELES, CALIFORNIA.

CONVEYER.

' Application filed Maren 1e,` 1920.' seria; No. 366,346.

To all whom t mag/,concern Be it known that I, ORLANDO J. Boos, al

citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful lmprovements in Conveyers, of which the vfollowing is a. specification.

This invention relates toI conveyers and more particularly to a comb-ined vertical and horizontal conveying system fo-r the efcient handling of objects to be transported from one level to another as from one story to another in buildings and from one discharge end of the vertical transfer on to means for making a horizontal transfer;

and the invention consists of the construction, the combination and in details and arrangements of the parts an embodiment of which invention is illustrated in the accompanying drawings and described and claimed herein.

Figs. 1, lA and 1B are fragmentary views showing when combined an elevational and partially sectioned view of the vertical and horizontal conveying means.

Figs. 2 and 2A are vertical elevation and sectional views of fragments of the apparatus looking in aplane at right angles to F iO. 1.

ig. 3 is a plan and sectional view on line 3--3 of Fig. 1A; and Fig. 3A is a continuation of Fig. 3. l

F ig. 4 is a section on line 4-4 of Fig. 1.

Fig. 5 is a side elevation and partial sectional view of the head structure of the vertical conveying means. i

The apparatus is primarily designed for the transfer of soiled dishes in public or private institutions where the soiled dishes are to be carried from an upper floor toa lower floor in large quantities with as rapid action as is consistent with safety and economy and are to be transferred from the dischargeend of the vertical conveying means in a substantially horizontal plane to a wash room where the soiled dishes are automatically discharged from vthe horizontal con- The system be driven by power derived from a motor 2, Fig.v 1A, the pulley of which ldrives a belt 3 engaging and driving a larger pulley 4 secured on a shaftl 5 on which there is provided a worm 6 engaging a lworm wheel 7, Fig. 25, secured on a countershaft 8, the shafts 5 and 8 being suitably journaled and supported on a substantial framework generally indicated at 9 and comprising such upright and such horizontal members as may kbe requisite according to the installation ofthe system.

One end of the counter shaft 8 is provided with a pinion 10 engaging a bevel gear 11 secured on a transverse shaft 12mounted in suitable bearings 13 provided on the framework, and the bevel gear 11 engages and drives a pinion 14 secured on an' l oblique shaft 15 in suitable bearings 16. On the lower end of the shaft 15 there is secured a pinion 17 engaging a corresponding pinion Y 18 secured on a transverse lshaft 19 having suitable bearings in the frame.

On the transverse shaft 12 there is secured a pair of sprocket wheels 20 and each of these engages a respective sprocket chain21 and 22 extending in parallelism upwardly and engaging head sprockets 23 secured on a head shaft 24 mounted in adjustable bearings 25 engaged b-y jack screws 26 mounted in fixed nuts or threaded parts 27 attached to the head structure 'of the frame 9.

The set of chains 21-22 is transversely connected at suitable po-ints by substantial plates hereinaftery termed runnersy designated at 30, theseI plates being connected to the respective chains by carrier blocks 31 provided on the chains 21-21, andthe runners have on their front faces bracket arms 32 which arms together with the runner plates` 30 may be secured to the carrier blocks 31 as by bolts 33. The `runner plates 30 are normally positioned to lie substantially flatwise along and across the connected portions of the` chains 21 and 22. 4

As clearly shown in Fig. 5 the brackets 32,

a set of whichis attached to the outer face of each runner 30, have, each, a pivot 34 on which there is mounted a'swinging arm'g35 preferably made of channel cross section-so spective arms 32, and the web portion of each'arm 35 is designed to be supported upon the upper surface of the bracket 32 when the severaly arms 35' are positioned as that the flanges straddle the sides of the rei shown in Fig. 5 and on the downwardly movingy stretch of the conveyer chains 21-22.

As shown in Figs. l and 4, the vertical conveyer belts 21 and' 22 pass along vertical guide rails or'corner tra-cks 36, the upwardly moving stretches of the conveyer chains ybeing shown to the left of Fig. l and the chains shown as bearing against the adjacent corner tracks 36 whilethe downwardly moving stretches ofthe chains on the righthand side of the column structure are caused to move in a common vertical plane as the runner members or plates 80 pass into a channel formed by 'suitable guide means comprising angle members or tracks 37 having. flanges spaced suitably from the adjacent Hanges of the contiguous cornerv tracks 36 so that the downwardly moving stretches of the sprocket chains Y21--22 successively bring the vrunners 30 from an indeter-v minate position on the upwardly moving 'stretches over the head sprocket wheels on the shaft 24:. As the plates enter the guideways formed by the guide rails 36-37 the runners become vertically disposed with the bracket arms 32 extending horizontally and with the arm members 35 resting horizontal-ly thereon in a coordinate position. So that a tray, indicated at T in dotted lines in certain of the. figures, can be readily supported in a horizontal position on a group of thearms 35 as the successivel group of arms move into register with the wall opening, indicated at W in Fig. l, that is arranged at any suitable elevation and at a convenient loading' station to permit the trays or carriers in which the objects to bev transferred are placed. j

The supporting yarms 35 are preferably provided with a cushioning or padding means such'as aV strip of leather or other suitable material indicated at 352l appropriately attached to the arms and forming therefor a vbed on which the receptacle T may rest. y s

The downwardly moving groups or sets v of carrying arms 35, which arms in a coinmon group are suitably spaced as plainly shown in Fig. 4., pass a horizontal plane in which there is arranged a horizontal conveying` means comprising a.I set of sprocket chains 40, there being shown in Fig. 3 a set comprising four of the chains each chain arranged in a vertical plane with its length arranged and guided over a series of sprocket and` guide wheels.

The chains 40 have a downwardly extending bight in Fig. 1A passing around a master or driving sprocket 4:1, of which there is one for each chain d0, these sprockets being secured on the shaft 19 that is driven by the bevel pinion 17-18. The chains d() each pass downwardly to the master sprocket wheels il from idler wheels 42 on a tra-nsverse shaft t and pass diagonally from the master sprocket wheels 41 up to a set of guide wheels t each individually supported on abracket arm l5 extending from a suitable support/lse as to hold the wheels let in the spaces between the carrying arms 35 of each group of arms, so that as the arms 35 of a group carrying a receptacle T pass below the top horizontal stretches of the baits Li-(i the carrier or tray will be deposed on these upper and co-planar stretches which move in the direction indicated by the arrow a, F it, to convey away horizontally the deposed receptacles or trays.

The horizontal stretches of the conveying chains i0 are each supported andguided in trough-shaped guides i? extended to a suitable distance and terminating at a discharge station indicated at D in Fig/5A which 'is a continuation of 3. The bottoms of the guide rails l? may be provided with a renewable liner such as a strip or strips of wood indicatedat 7a.

At the discharge station or end of the conveyors -fi-O there arranged a deflector in the form of an upright cam or fixed' guide flange beneath the lower edge of which the several ccuvcyer chains d0 pass around a contiguous direction wheel i9 on a shaft 5() mounted on adjacent posts of the frame 9. From the direction wheels i9 the chains pass over idlers 5i mounted on a common cross shaft 52 and thence to other idlers 53 also on a common shaft 5d and thence to the direction wheels d2.

The deflecting flange or cam member i8 isV obliquely disposed so as to intercept the incoming trays Tand divert them on tothe receiving table or bench B from which they may be carried 'to a dishV washing machine or may be otherwise disposed of according to the nature of the objects being transferred and handled. f.

The bracket arms 35, while they are pivoted on the brackets 32 at the pivots 34., preferably have a sufficient friction between the connectingmeans so as to normally hold the arms in the position shown. in Fig. l, but in the event of the apparatus becoming stalled and any; obstacle vengaging the bracket arms 35 these can yield vupwardly as indicated by the arrow I), Fig.l 5. j

From the above it will be seen Avthat I have provided an apparatus that is comparatively simple, that is reliable in 'operation and durable and effective and will` handle rapidly and operate with, large j carrying capacity with a minimum of power consumptiony and also will operate to change the direction of travel ,or path in which the objects are being transferred, The guide wheels il are, preferably, made duplicate halves orsections andare arranged on opposite sidesI of the contiguous bearing forming portion ofthe end of its respective bracket arm so that-by this construction a minimum Width of structure is secured as is desirable because of the projection of the bearing arms 4:5 with their pulleys or guide wheels 4:4 extending in between the carrying arms 35.

Various changes may be made without departing from the spirit of the invention as claimed.

`What is claimed is:

l. A conveying apparatus comprising a vertically arranged set of chain conveyers with cross plates each arranged parallel to given carrier links of the cha-in, brackets attached to each plate, and receiving arms pivotally attached to the brackets.

2. A conveying system comprising a set of sprocket chains having bracket arms arranged to extend perpendicular to the chains, and another set of chains set at an angle to the first and having portions extended between the said bracket arms so that as the latter pass the extended portions of the chains the. objects will be transferred from one to the other, the bracket arms being resiliently yieldingly attached to the respective chains of the second set.

3. A conveying system comprising a set of sprocket chains having bracket arms arranged to extend perpendicular to the chains, another set of chains set at an angle to the first and having portions extended between the said bracket arms so that as the latter pass the extended portions of the chains the objects will be transferred from one to the other, cross members connecting the sprocket chains, and guides for the said members whereby the arms are positioned in a predetermined manner for a portion of their orbital movement, said guides comprising channel members having a flared upper end to facilitate the entrance of said cross members into the guide portion of said channel members.

4. A conveying system comprising a vertically arranged set of chain-conveyers with cross plates each arranged parallel to given carrier links of the'chains; brackets at.

tached to each plate; receiving arms pivotally attached to the brackets to lie in a cornmon plane; and a set of conveyer chainsat an angle to the vertical set and so arranged that the arms pass between the last named set to deposit objects thereon.
